Evaluation of canal water conveyance and on-farm water application for a small-scale irrigation scheme in Ethiopia

This study was conducted to identify and understand the current level of canal water conveyance and on-farm water application efficiency of Lemchek-Sewur small-scale irrigation scheme in Ethiopia. The water conveyance efficiency of canals was determined by estimating discharge at different segments. On-farm water application efficiency was evaluated from the amount of water actually applied and from soil moisture...

ANNs, SVM and empirical methods for modelling reference evapotranspiration with limited climatic data in the city of Xai-Xai, Mozambique

Reference evapotranspiration (ETo) is useful for water management, calculating crop water requirements and irrigation scheduling. ETo was estimated from 5 empirical methods based on temperature, 5 based on solar radiation and on Machine Learning Technique (MLT). The MLT model consisted of Artificial Neural Networks (ANNs) and Support Vector Machine (SVM), with 6 architectures each one. The MLT and empirical methods were...

Evaluating Potential Impacts of Climate Change on Surface Water Availability of Upper Awash Sub-Basin, Ethiopia

Climate change alters regional hydrologic conditions and results in a variety of impacts on water resource systems. Such hydrologic changes will affect almost every aspect of human well-being. The economy of Ethiopia mainly depends on agriculture; and this in turn largely depends on available water resources. The aim of this study is to assess the impacts of climate change on surface water availability of Upper Awash River...

Efficiency of empirical methods for reference evapotranspiration estimation in the district of Vilankulo, Mozambique

Precise quantification of reference evapotranspiration (ETo) is crucial for calculating crop water demand. Eight empirical methods based on temperature and six on solar radiation were evaluated against Penman-Monteith FAO 56 method based on: Mean Bias Error (MBE), Root Mean Square Error (RMSE), Willmott coefficient (“d”), determination coefficient (R2) and the Student’s t-test. The meteorological data of Vilankulo district...

Surface water distribution among the provinces of Pakistan

The water resources sector is both the lifeline and the gear of development in Pakistan. The main source of water in Pakistan is the ‘Indus River System’. Under the ‘1960 Indus Basin Treaty’ with India, Pakistan was entitled to the flow of three western rivers (Indus, Jhelum and Chenab), with occasional spills from the eastern Rivers Sutlej and Ravi diverted upstream by India. The average annual inflows of the western and...

The removal of benzene toluene, ethyl benzene and p-xylene (BTEX) from aqueous solution by granular activated carbon

The removal of benzene toluene, ethyl benzene and p-Xylene (BTEX) from aqueous solution using granular activated carbon (GAC) was investigated in the study. To determine the efficiency of GAC, the removal of BTEX by GAC was carried out in relation to contact time, adsorption dosage and pH. Comparative studies of batch and column setup and adsorption/desorption were done to determine its efficiency in respect to its...

Quantification of water balance using a lysimeter in Mexico

Under conditions of high pressure on water resources, it is essential to quantify the water balance. There are tools to perform the water balance, but unfortunately, they are expensive and hardly accessible in developing countries. The objective of this study was to quantify the water balance using a low-cost lysimeter (LCL). Rainfall was measured using rain gauge. Soil water content (SWC) and infiltration were measured...

Hydrological model performance across altitudes, climates and catchment scales

Water resources management decisions are made based on information from predictive models that are capable of simulating the behaviour of hydrological systems. More of these models are in use today and it is becoming increasingly difficult to choose which model to use for particular space and time scales as well as climate. In addition, as a result of climate change there is an increase in the degree of randomness in...
