WATR07009: Analysis of Water Quality in Irish River Basins

This report provides a detailed analysis of water quality in Irish River Basin Districts, addressing key aspects such as threats to freshwater resources, the definition of Good Surface Water Status according to the Water Framework Directive, and the significance of water bodies in this context. It covers thermal stratification in lakes, the water budget equation, and abiotic environmental factors. Furthermore, it discusses protected areas as defined by the Water Framework Directive, water quality classification for rivers, and the differences between Artificial Water Bodies (AWB) and Highly Modified Water Bodies (HMWB). The report also outlines the hydrological cycle, main river systems in Ireland, actions from the River Basin Management Plan, and bodies involved in its second cycle. A comparison of natural and urban water cycles is presented, along with an explanation of Sustainable Drainage Systems (SuDS) and soft engineering strategies for flood management. Desklib offers a range of study tools and resources for students.

Question 1
Q 1(a) Threats to freshwater resources

 Pollution
 Destruction of freshwater eco-systems
 Impact of climate change
 A resurgence of water related diseases
Q 1(b) Defining Good Surface Water Status
As per Water Framework Directive, “A good surface Water Status means that there
are no concentrations of various priority substances which exceed the relevant EQS which are
established in Environmental Quality Standards Directive 2008 (O’Boyle and et.al., 2019). It
aims to protect the sensitive species from direct toxicity as well as including the predators
and humans through secondary poisoning”.
Q 1(c) Significance of water body
The Water Framework Directive needs every member for protecting and improving
the water quality in all waters so that it can attain the good ecological status. It is committed
towards attainment of appropriate quantitative and qualitative status of all the water bodies
such as ocean as well as including marine water (Stefanidis and et.al., 2019).
Q 1(d) Thermal stratification in lakes
Figure 1The phenomena of a sudden change in temperature at certain depths in a lake or pond is known as
Thermal Stratification. 2021.

Q 1(e) Water budget equation in terms of equation
Water budget equation is an equation relating to the components which can be explained as
the P+ Qin = ET+ Change in S+ Qout (A1)
Here, P refers to Precipitation, Qin refers to the water flow in watershed, ET stands
Evapotranspira Tion which is the sum of evaporation from soil, plants and surface water
bodies. Change in S stands for changes in water storage. In the last Qout refers to water flow
out of the watershed.
Q 1(f) Abiotic factors of the environment
The abiotic factors of environment are the non-living chemical elements and physical
elements which are involved in eco-systems such as water, soils, are and minerals etc.
(Wiering and et.al., 2018).
Q 1(g) Protected areas as defined by the Water Framework Directive with 3Examples
As per Water Framework Directive defines the protected areas are the areas which require
special protection or security under EC Directors. It is also referred to the waters which are
also used as the abstraction of drinkable water.
For example: Surface water, Groundwater and drinking water.
Q1 (h). Water quality classification for river under 5 ecological status
WFD
Ecological
status
Water quality
(Description)
Q-Values
High It means the water quality is near natural conditions and
provides multiple beneficial uses due to no human activity
Q1
Good Due to human activity slightly change from natural
conditions however, provides various beneficial uses.
Q2
Moderate Due to human activity moderate changes. Some restrictions
on beneficial uses of water body
Q3
Poor Major changes from natural conditions caused by human Q4

interventions. Various restrictions on beneficial use of
water.
Bad Severe changes from natural conditions as well as
significant restrictions on beneficial uses of water body.
Q5
Q 1(i) Difference between AWB and HMWB
Artificial Water Body (AWB) Highly Modified Water Body (HMWB)
They are created in the places where water
bodies did not existed before. They are not
created by physical alternations directly or
existing water bodies (O’Donoghue and et.al.,
2021).
They are the result of physical alternations
due to human activities which are
substantially changed in character. So they
cannot meet the ecological status.
Q 1(j) 3 channel features of rivers
 The river moves through upper course but it cuts downwards
 The river channel is narrow
 The vertical erosion helps river in creating steep sided-V shaped waterfalls or valleys
etc.
Question 2
Q 2(a) Hydrological cycle
It is the sum total of all the procedures in which water moves from ocean’s surface and land
surfaces to the atmosphere and back in the form of precipitation as well.

Figure 2Hydrological Cycle, 2021
Q 2(b) 2 main types of river systems in Ireland
 River Shannon- It is the longest river which rises in Northwest country of Cavan. It
flows for approximately 161 miles to enter Atlantic Ocean.
 River Barrow-It is the second longest river in Ireland which flows for about 120 miles
to enter Atlantic Ocean.
Q 2(c) 3 actions to be taken in the River Basin Management Plan for Ireland
2018-2021
 Improvement of waste water treatments
 Leakage and conservation reduction
 Collaborative Advisory and sustainability support programme.
Q 2(d) 2 bodies established for the 2nd cycle of the River Basin Plan and how they
communicate and engage with stakeholders

Bodies established for 2nd cycle of the River Basin Plan are EC of European Parliament and
the Council. They communicate with the stakeholders through by promoting the participation
of stakeholders and the public in River Basin Plan which enables them to engage freely and
equally in management through the support of democratic processes (Tahar and et.al., 2018).
QUESTION 3
Q 3(a) Using diagrams, compare and contrast the natural and urban water cycles
Urban water cycles

Natural water cycle

Q 3(b) Sustainable Drainage Systems (SuDS)
Sustainable Drainage systems are the approaches or collection of water management
practices and approaches which focus on modern drainage systems with natural water
procedures. It also makes efforts to make the urban drainage systems more compatible with
natural water components (Daly and et.al., 2017).
Q 3(c) 4 pillars of SuDS design
 Water quality- It is the management of quality if runoff in order to eliminate pollution
 Biodiversity- It is creating and sustaining better places for nature
 Amenity- It is creating and sustaining better places for humans
 Water quantity- It is related to control on quantity of runoff
Q 3(d) Explaining the statement and 3 types of soft engineering strategies for flooding

As the soft engineering options are considered to be less expensive than the hard engineering
options. It makes them more sustainable and long term lasting as well as creates less impacts
on the natural environment (Fraser, Brickell and Kalin, 2020). The soft engineering flood
management strategy often include low costs nature as compared to the hard engineering
strategies as it involves more materials and consumes time to put in place. So soft
engineering strategies are low maintenance thus are more sustainable.
The three types of soft engineering strategies for flooding involves:
 Floodplain zoning
 River restoration and
 Flood warnings and preparation
