The impact of human water management on river discharge is increasingly viewed as a missing process in Earth system modeling. Models which have attempted to include it are generally at coarse resolution and uncoupled the atmosphere. We propose describe high spatial using ORganizing Carbon Hydrology In Dynamic EcosystEms concept hydrological-transfer-units routing parametrization. Irrigated area...

Check dams are one of the structures used to control debris flows. In this study, in order to evaluate the effect of hydraulic parameters on debris sediment trapping rate by the slit trapezoidal check dams with different angles, and to develop an empirical relation for determination of trapping coefficient of the dam reservoirs, three physical models of the check dams were used. The tests were ...

All over the world, dam managers are constantly confronted with siltation of reservoirs. This natural phenomenon represents a menace to safety dam; because sediments deposited amplifies load applied and shut off dam’s bottom outlet. It also reduces usable capacity reservoir degrades quality water stored (pollution, eutrophication, turbidity, etc.). In arid semi-arid countries like Morocco, de-s...

As in many other cities, urbanization coupled with population growth worsens the water supply problem of Addis Ababa, Ethiopia, with a water supply deficit of 41% in 2016. To investigate the potential contribution of rooftop rainwater harvesting (RWH) from large public institutions, 320 such institutions were selected and grouped into 11 categories, from which 25-30% representative 588 rooftops...

Reservoir sedimentation has been a global bottle neck in maintaining the design storage capacity of reservoirs. leads to reduction original which affects irrigation, hydropower, flood control, drinking water supply and recreational activities. Introduction mechanized farming without due regard nature environment is aggravating erosion sediment problem. This study discussed analyzed most importa...

Abstract. With rapid population growth and socioeconomic development over the last century, a great number of dams/reservoirs have been constructed globally to meet various needs. China has strong economical societal demands for constructing dams reservoirs. The official statistics reported more than 98 000 in China, including nearly 40 % world's largest dams. Despite availability several globa...

The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower [1]. The dam will serve the Northern areas of Greater Beirut Mount Lebanon [2]. The project site is located in highseismicity region. The Peak Ground Accelerations ar...

BACKGROUND Reservoirs created by damming rivers are often believed to increase malaria incidence risk and/or stretch the period of malaria transmission. In this paper, we report the effects of a mega hydropower dam on P. falciparum malaria incidence in Ethiopia. METHODS A longitudinal cohort study was conducted over a period of 2 years to determine Plasmodium falciparum malaria incidence amon...

This paper was motivated by the 25th anniversary of the publication of Marc Reisner's book, Cadillac Desert: The American West and its Disappearing Water. Dams are ubiquitous on rivers in the United States, and large dams and storage reservoirs are the hallmark of western U.S. riverscapes. The effects of dams on downstream river ecosystems have attracted much attention and are encapsulated in t...

Brazil has a history of blooms and contamination of freshwater systems by cyanobacterial toxins. The monitoring relevance of toxins from cyanobacteria in reservoirs for public supply is notorious given its high toxicity to mammals, included humans beings. The most recurrent toxins in Brazilian water bodies are microcystins (MC). However, the recent record of cylindrospermopsin (CYN) in northeas...
