“…Remote sensing is a new technique used to map water quality parameters, such as chlorophyll content and suspended matter (Arenz et al 1996;Dewidar and Khedr 2001;Vincent et al 2004). This technique can be applied for lakes and reservoirs (Lillesand and Kiefer 1994) and tropical coastal areas (Ruiz-Azuara 1995). In situ monitoring, water quality modelling and spatial distribution of water quality parameters using geographical information system (GIS) can provide an insight about hydro-geochemistry and ecology of water systems (Rewanet 1994;Allewijn et al 1995).…”

Hydrogeochemical characteristics and assessment of water quality investigations have been carried out at Abha, located in Saudi Arabia, where Al-Saad Lake represents a rare example of natural endorheic lake. The ecosystem within and around the Al-Saad Lake including catchment area is of great social, cultural, aesthetic, environmental and economic values to Abha. The result obtained in this investigation inferred that the cations in water i.e. sodium and iron are within the permissible limits but magnesium and potassium have exceeded the permissible limit. Whereas anions such as nitrate and fluoride are within the permissible range but chloride and sulphate have exceeded the permissible limits. The concentration of cation, magnesium (Mg) and potassium (K) in the lake water has exceeded the desirable range (30, 10 mg/L, respectively). This may be due to weathering and transported from rocks and particularly from sulphate deposits such as gypsum and anhydride and subsequently ends up in water. The concentration of anion, Sulphate (SO 4 ) and chloride are above the desirable limit. The major source of bicarbonate are the carbonate rocks containing calcite (CaCO 3 ) and dolomite (CaMg (CO 3 ) 2 ), Calcium (Ca) and Magnesium (Mg) can also be transported from Ca-silicates and Mg-silicates. The piper trilinear plot suggests the increase of Ca and SO 4 contents is attributed to dissolution of gypsum and anhydrite, which are commonly found in the quaternary formations of watershed (wadi). Ion exchange, dissolution of calcite, semi-arid climate, alkaline condition and weathering are responsible for high concentration of ions exceeding the desirable limit of the study area.

“…Land use change effects on soil loss were estimated using RUSLE and GIS models by Yueqing et al (2011) which results in increasing dry farmland and decreasing forest and grassland and the changes have significantly affected soil erosion. Shi et al (2004), Ouyang and Bartholic (2001), Mallick et al (2014) and Tunc et al (2014) investigated soil erosion risk using RUSLE and GIS and displayed the results as erosion risk maps and they confirmed that the model is practical for soil conservation plans and natural resources management. Determination of soil erosion rate in each sub-watersheds of Meki river watershed is an essential step in soil and water conservation programs and integrated watershed management projects.…”

Background Water erosion, upland degradation and deforestation are the key environmental problems in Meki river watershed where this study was conducted. This study assessed the land use land cover change (LULCC) over the last 30 years, examined the contribution of Enset-Based land use system (EBLUS) to manage soil erosion problem for sustainability of Lake Ziway and suggested appropriate management interventions for the watershed ERDAS imagine 2014, Geo-statistical interpolation and RUSLE model was devised for LULCC detection and analysis, for different spatial inputs and soil loss modeling respectively. Result Meki river watershed covers 2110.39056 km² of area which is dominantly covered by cultivated land use system (41.5%), Enset-Based land use system (EBLUS)(10.65%), Bush and Chat land use system (25.6%), Forest and plantations land use system (14.14%), built up (7.4%) and water bodies (0.75%). Severity class of High to severe range (18-125tha-1yr-1) recorded in the sub-watersheds irrespective of the land use systems and facing sever degradation problem that increase in soil loss in all land use systems from 1987 to 2017. The average soil loss of 30.5tha-1yr-1 and 31.905tha-1yr-1 recorded from Enset growing zones and non-Enset growing zones of the watershed respectively.Conclusion Enset-Based land use system (EBLUS) saves significant amount of soil despite the steepness of the slopes of the Enset growing zones of the watershed. Hence, expansion of EBLUS can contribute in sustaining Lake Ziway by reducing soil loss rate and sedimentation problem for ecological sustainability of the watershed. Therefore, separate land use policy and awareness creation are mandatory for such EBLUS expansion, integrated watershed management and conservation of the natural environment.

Background Water erosion, upland degradation and deforestation are key environmental problems in Meki river watershed. . The study assessed the land use land cover change (LULCC) over the last 30 years, examined the contribution of the indigenous Enset-Based land use system (EBLUS) which was not studied so far in reducing soil erosion and preventing Lake Ziway from sedimentation. Based on the outcomes, the research recommended appropriate management interventions based on priority mapped to sustainably manage the watershed. GPS based Ground truth data sampling and collection, Geo-statistical interpolation and RUSLE model were applied for soil erosion modeling. The LULCC detection and analysis was conducted to generate the spatial inputs using ERDAS Imagine 2014. Result Meki river watershed has 2110.4 km² of area which is dominantly covered by cultivated land use system (41.5%), Enset-Based land use system (EBLUS)(10.65%), Bush and Chat land use system (25.6%), Forest and plantations land use system (14.14%), built up (7.4%) and water bodies (0.75%).

Hence, expansion of EBLUS can contribute in sustaining Lake Ziway by reducing soil loss rate and sedimentation problem for ecological sustainability of the watershed. Therefore, separate land use policy and awareness creation are mandatory for such EBLUS expansion, integrated watershed management and conservation of the natural environment in the watershed.
