Over the past half-century, the risk of urban flooding in Dar es Salaam has increased due to changes in land cover coupled with climatic changes. This paper aimed to quantify the impacts of climate and land-cover changes on the magnitudes and frequencies of flood runoffs in urban Dar es Salaam, Tanzania. A calibrated and validated SWAT rainfall-runoff model was used to generate flood hydrographs for the period 1969–2050 using historical rainfall data and projected rainfall based on the CORDEX-Africa regional climate model.
Implications of Climate Change for Water Resources Development in the Ganges Basin
This paper presents the first basin-wide
assessment of the potential impact of climate change on the
hydrology and production of the Ganges system, undertaken as
part of the World Bank’s Ganges Strategic Basin Assessment.
A series of modeling efforts, downscaling of climate
projections, water balance calculations, hydrological
simulation and economic optimization, inform the assessment.
The authors find that projections of precipitation across
Potential of natural technologies for decentralised wastewater management in India.
High population growth, increasing urbanization and rapid economic development are exerting pressure on the already scarce water resources in India. Treatment and reuse of wastewater can play an important role in addressing some of the urban water challenges. Conventional treatment plants have many challenges, therefore, natural treatment systems (NTSs) are viewed as a cost-effective alternative, which are more suitable in the Indian context.
