2EXECUTIVE SUMMARYThere is a sum of hydrological models that have been established to meet the needs of theenvironment. Different regions experience rainfall in different measures, as a result there is greatneed to strategize on the flood protection. Floods refer to the high run-off events. Runoff instreams is the integration of several upstream processes in a watershed or river basin based onthe topography. The collection of hillslopes and channels generate runoff from a given pixel andultimately contribute to streamflow and they can be overland runoff and subsurface runoff. Thereason why a model is developed for the rainfall-runoff procedures of hydrology is as anoutcome of the confines of hydrological amount techniques. This paper implements the SimHydmodel in the Rainfall Runoff model library to perform the sensitivity analysis and simulation onthe provided data. The second part of this project paper discusses the reservoir and its performance analysis.Dams tend to be quite important and relevant to civilization in environments that offer the typesof immoderations in Australia. Building dams has been known to cause many ecologicalproblems in many of the advanced world. There are many reasons why dams are built are forwater supply, irrigation, hydro-power, flood control, and water quality. The same modelinformation was used to demonstrate the performance of the man-made dam.

4INTRODUCTIONMany researchers have conducted case studies to progress their comprehension and the level ofinformation concerning the hydrological procedures intricate in the rainfall-runoff revolution.The research carried out provides solutions to the water problems and proper environmentalconservation. Initially, the hydrology research collected data and performed the analysis on penand paper. With the advent of technology, it is possible for the researchers to perform veryadvanced analysis[CITATION Doo \l 1033 ]. The analysis provides conducive grounds foradvancement of the rainfall-runoff models. The rainfall-runoff model is used with data from asocket rainfall gauge and records on daily potential evapotranspiration (PET) to forecast floodvolume and peak rates of the overflow for small drainage areas. The new technology has enabledthe analysts to perform simulations on a larger scale. There are three basic components of thehydrologic cycle namely,(i)Infiltration(ii)Surface run-off(iii)Antecedent moistureThere are a set of hydrological models that have been developed to meet the needs of theenvironment. Different regions experience rainfall in different measures, as a result there is greatneed to strategize on the flood protection. Floods refer to the high run-off events. Runoff instreams is the integration of several upstream processes in a watershed or river basin based onthe topography. The collection of hillslopes and channels generate runoff from a given pixel andultimately contribute to streamflow and they can be overland runoff and subsurface runoff. Thereason why a model is developed for the rainfall-runoff practices of hydrology is as an outcomeof the confines of hydrological measurement methods. Before the new simulation techniquesevolved, researchers had a restricted range of measurement practices and a limited range ofmeasurements in both space and time. Different models seek to provide different means ofnumerical extrapolation or forecast on the data obtained for proper decision making. Hydrologysystems are a bit complex to analyze and as a result, each researcher analyses data using his orher own perceptual model. Owing to the difference, analysts hardly agree on the crucialprocesses. In addition to that, most of the water tends to flow on the bedrock hence thesubsurface flow process brings about a hitch in developing great models for research.
