A dam spillway is a hydraulic structure that appropriately and safely diverts the outflow to downstream, so that the dam stability and passing of flood flows can be guaranteed. Compared to straight crest spillway, an Ogee spillway with curvature in plan in a fixed-width can pass more flow. Therefore under the low hydraulic heads and the need for a smaller place in plane, they are considered as ...

Abstract Due to the fact that one of important ways describing performance basins is use hydrological signatures, present study investigates effects climate change using signatures in Azarshahr Chay basin, Iran. To this end, Canadian Earth system model (CanESM2) first used predict future (2030–2059) under two Representative Concentration Pathways (RCP2.6 and RCP8.5). Six signature indices were ...

The economic development, livelihood and drinking water of millions people in the central plateau Iran depend on Qarah-Chay River, but due to a lack inappropriate monitoring, it has been exposed destruction pollution. Consequently, an assessment river’s quality is utmost importance for both management human health maintenance safe environment, which can be achieved by determining best locations...

Bencana alam yang berhubungan dengan air kerap terjadi di Indonesia, seperti banjir dan kekeringan. Para ahli menyebutkan salah satu faktor utamanya adalah gangguan pada siklus air. Untuk meminimalisir bencana-bencana itu terjadi, diharuskan untuk lebih memperkenalkan kepada khalayak umum agar bisa dimengerti bahwasanya sangat dipengaruhi oleh kegiatan manusia. Siklus hidrologi sirkulasi tanpa ...

Construction of managed aquifer recharge structures (MARS) to store floodwater is a common strategy for storing depleted groundwater resources in arid and semi-arid regions, as part integrated water management (IWRM). MARS divert surface groundwater, but this can affect downstream fluvial processes. The impact on processes was investigated study by combining remote sensing techniques with hydro...
