![]() There was no sign of the old bearings or cage when I opened it. It was in there so good the tacks would break off and take some race with them. Nothing to grab so I tacked some welds to the inside. Might get an answer to my rubber washer question.ĭamn that was just as nasty as some of the pics I've seen. The paper intends to stress the benefits that can be obtained through synergies between UNESCO programs operating within the same river basin.I posted some of this in my first TDI project thread.īut it seems like the info would be better placed here. Programs such as HELP and Ecohydrology can effectively support the planning process by improving dialogue between different disciplines, sectors and perspectives on water, resulting in a much richer consideration of the issues and possible solutions. This challenge has proven to be more difficult than expected for European countries. Under the European Water Framework Directive, river basin plans must integrate ecological, social and economic dimensions. This paper discusses how this particular synergy can be beneficial to the planning process. More opportunities for cooperation in the Guadiana basin were created with the additional classification of the basin as a Ecohydrology Reference Basin, in 2010. The Guadiana River, on Portugal and Spain, is a UNESCO HELP basin, and in July 2009, an international HELP forum brought to the Guadiana experts from all continents to discuss, with the planning team and local community, experiences from river basins around the world. Complimentarily, the UNESCO Ecohydrology Programme aims to use knowledge about the integrated relations between hydrologic and biologic processes. UNESCO HELP is a cross-cutting programme aiming to improve the links between hydrology and the water needs for society. International agencies such as UNESCO are promoters of this dialogue. This is receiving increasing attention through cross-cutting synergetic cooperation between hydrologists and other disciplines. In the context of growing demand, loss of quality, increasing regional scarcity, and global climate uncertainty, sustainable water management, as well as more integrated approaches to water planning, are crucial. Groundwater resources are under escalating pressure from urbanization, natural gas drilling, and predicted intensifying of droughts due to global climate change." Parker County is within the Upper Trinity Groundwater Conservation District (UTGCD) and is largely a rural area with many residents dependent upon private shallow, groundwater wells. The Trinity Aquifer supplied 73% of the area’s groundwater in 2000, with the aquifer outcrop zone being highly susceptible to anthropogenic sources of contamination. The newly created PGMA’s population is expected to increase from 5.5 million in 2000 to 9.5 million by 2030 with projected water needs rising from 1,677 million m3 in 2000 to 3,034 million m3 by 2030 according to a study by Texas Commission on Environmental Quality (TCEQ). "Introduction/Problem Identification In 2007, a 20-county area encompassing the Dallas-Fort Worth Metroplex was designated by the State as a Priority Groundwater Management Area (PGMA) in need of implementing strategies for groundwater conservation. The results show that he hypsometric curves of those watersheds can be classified in three groups and the concavity of the hypsometric curve affects the peakedness of the topographic index distribution. Hypsometric attributes and topographic index statistics were calculated to compare watersheds morphology and to interpret the effect of hypsometric curve shape on the topographic index distribution. ![]() The hypsometric curve and topographic index were used as geomorphological indicators. In this paper, as the first stage of such basic information before analyzing hydro-metrological variables, we focused on the geomorphological characteristics of fifteen small hillside river basins in the semiarid region of Tunisia. In order to reduce the uncertainties in water resources management of the small hillside river basins in semiarid region, studying the basic information of the river basins which prescribes the fundamental behavior of the basins has a very important role. However, flash floods and severe soil loss which jeopardized the function of those small hillside reservoirs are reported. Since then, quite a few small hillside reservoirs have constructed. Tunisian government has introduced a political water resources plan constructing small hillside reservoirs since 1990. The small hillside river basins in the semiarid region of Tunisia are very crucial for the sustainability of the water resources, especially for agricultural irrigation water.
