The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities, or the deterioration of water quality resulted from pollution emissions, or both.
This study evaluated the hydrological effects of operation of a diversion hydropower facility on the Correntes River in Brazil (mean discharge 73 m3 s−1), which is potentially important because of the ecological implications for the floodplains of the Pantanal into which it flows.
(3) Higher flood risk due to alterations of hydrological extremes will pose a threat to the existing hydraulic facilities.
Some of these facilities, however, are poorly designed in terms of hydrological and hydraulic performance, which strongly affects their treatment capacity.
The model calculated a detailed soil infiltration process in bioretention with hydrological conditions (e.g. unsaturated and saturated soil) and hydraulic facilities (e.g. riser and underdrain) and also generated an optimized plan using Flow Duration Curve (FDC).
Frequency analysis of hydrometeorological and hydrological extremes is needed for the design of hydraulic and civil infrastructure facilities as well as water resources management.
The software has facilities to zoom on a river basin, calculate a variety of hydrological characteristics, define or select any category of ecosystem protection, calculate the associated environmental flow duration curves and time series and display both.
In 1998, the Ministry of Construction began to investigate rainwater utilization facilities throughout Japan, as part of a wider program of preserving the urban hydrological cycle.
Irrigation water is an important but missing hydrological cycle component in the region with intensive agricultural irrigation, due to the lack of monitoring facilities.
The supply challenges of Ghana's power sector are mainly seen in the periodic hydrological shortfalls as a result of the uncertain pattern on rainfall and inflows into the hydropower facilities.
