Ahmad, Mobin-ud-DinIslam, AminulMasih, IlyasMuthuwatta, Lal P.Karimi, PooladTurral, Hugh[Mapping basin-level water productivity using remote sensing and secondary data in the Karkheh River Basin, Iran]Mapping basin-level water productivity using remote sensing and secondary data in the Karkheh River Basin, Iran

This study was conducted to assess water availability and consumption in the Karkheh River Basin in Iran using secondary data and freely available satellite data. Precipitation was estimated using geo-statistical techniques while a Surface Energy Balance approach was selected for evapotranspirati...


Muthuwatta, Lal P.Ahmad, Mobin-ud-DinBos, M.G.Rientjes, T.H.M.[Assessment of water availability and consumption in the Karkheh River Basin, Iran using remote sensing and geo-statistics]Assessment of water availability and consumption in the Karkheh River Basin, Iran using remote sensing and geo-statistics

Well-targeted programs of conjunctive use of groundwater and surface water can help overcome the problem of both floods and droughts, or in other terms meet the water demands for domestic as well as irrigation needs during the dry season. Addressing this, a novel form of conjunctive use managemen...


Brindha, KarthikeyanPavelic, PaulLagudu, SurinaiduMuthuwatta, Lal P.Eriyagama, NishadiAmarnath, GirirajSmakhtin, Vladimir U.[Novel conjunctive groundwater-surface water management for controlling floods and droughts [Abstract only]]Novel conjunctive groundwater-surface water management for controlling floods and droughts [Abstract only]

Water productivity (WP) mapping is essential to evaluate the performance of current water use at the river basin scale. WP mapping is also essential to identify opportunities to improve the net gain from water by either increasing the productivity for a given consumption of water or reducing cons...

Two strategies are assessed to increase wheat production in the water-scarce Karkheh River Basin (KRB) in Iran to meet targets by the year 2025. The strategies proposed are (a) to increase yields in the current irrigated and rainfed wheat areas and (b) to increase the area under rainfed wheat thr...

In this study, streamflow (Qs) and satellite-based actual evapotranspiration (ETa) are used in a multi-variable calibration framework to reproduce the catchment water balance. The application is for the HBV rainfall-runoff model at daily time-step for the Karkheh River Basin (51,000 km2) in Iran....

The Tana River is one of Kenya’s most important rivers. It is the principal water source for Nairobi, the capital city, providing water for hydroelectric power generation and irrigation. Several of the flagship projects laid out in Vision 2030 - the blueprint that guides Kenya’s national developm...


Sood, AdityaMuthuwatta, Lal P.Silva, SandeepanaMcCartney, Matthew P.[Understanding the hydrological impacts of climate change in the Tana River Basin]Understanding the hydrological impacts of climate change in the Tana River Basin

In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resourc...
