The yields of the tropical rivers of Southeast Asia supply large quantities of carbon to the ocean. The origin and dynamics of particulate organic matter were studied in the Houay Xon River catchment located in northern Laos during the first erosive flood of the rainy season in May 2012. This cultivated catchment is equipped with three successive gauging stations draining areas ranging between ...

The results of four field surveys in Senegal are reported. 1. A snail survey in various parts of the Senegal River Basin, including the Senegal River, temporary rain-fed pools, swamps, irrigation canals and drains, ricefields and Lac de Guier was carried out. Three species of snails were commonly found: Bulinus guernei was the most common, occurring in permanent habitats, Bulinus senegalensis o...

The dynamics of aquatic macrophytes in intermittent rivers is generally related to the characteristics of the resistance and resilience of plants to hydrologic disturbances of flood and drought. In the semi-arid region of Brazil, intermittent rivers and streams are affected by disturbances with variable intensity, frequency, and duration throughout their hydrologic cycles. The aim of the presen...

Home and neighborhood are sight that attached to the memory of every child will provide a different experience for each them. A who lives in city has space from one village, as well those live by river on edge railroad tracks. This study aims trace meaning placeness children suburbs with weak economic conditions still living non-permanent homes. Placeness be tracked through resulting image. The...

Recent wetting in the Northern Great Plain (NGP) exerted strong influences on lakes and wetlands. However, influence of recent increase precipitation spatiotemporal variation surface water area is poorly understood Red River Basin (RRB, northern United States southern Canada). Here, we used a high-resolution global dataset to understand dynamics annual, total, permanent, seasonal extent RRB. Mo...

Erosion of the river banks in India have become recurrent event causing enormous problem for the people and the Government. With the increase of population along the bank of the rivers, the erosion of township, cluster of villages and important communication system, govt. resources are over exploited. Presently a large number of township, villages, human dwellings a number of important installa...

The goal of this study is to analyze the floristic patterns and the structure of disturbed and undisturbed upland forests, in Permanent Preservation Areas (PPAs) along the Moju river, in the Brazilian state of Pará. Trees with a diameter equal to or larger than 10cm at 1.30m from the ground (DBH) ≥10cm were analyzed for the upper stratum. For the middle stratum, individuals with DBH between 4.9...

This research studied the process of irregular urban occupations that occurred along Cuiabá River Permanent Preservation Areas (PPAs), as a key to understand its importance for sustainability. Its objective was study dynamics and socio-environmental impacts resulting from banks river cuts through two largest cities in Metropolitan Region Valley - RMVRC/MT, state capital Cuiabá, Várzea Grande.
