groundwater resources around the Wadi Baye area in order to determine its suitability for a different purpose such as irrigation and drinking. In addition by applying drip irrigation instead of sprinkle and surface irrigation methods, the land suitability of 1651.8 ha (43.8%) of this plain will improve. College, Osmania University, Hyderabad, India Omran proposed a simple method to assess the groundwater quality and to map its spatial variation in terms of suitability for irrigation in the Darb El-Arbaein area, Southwestern Desert, Egypt. This study proposes a water quality evaluation system to assess the aptitude of the Selangor River water for aquatic biota, drinking water production, leisure and aquatic sport, irrigation use, livestock watering, and aquaculture use. Each irrigation method has its advantages and disadvantages. 1. The results obtained from this research make it possible to evaluate the suitability of surface water for irrigation and to draw useful recommendations for dam managers and farmers. Clay soils with low infiltration rates are ideally suited to surface irrigation. The frequency, rate, amount and time of irrigation are different for different crops and also vary according to the types of soil and seasons. The results demonstrated that by applying drip irrigation method instead of surface and sprinkle irrigation methods, land suitability classes of 36790 ha (84.19%) for Fakkeh Plain will improve. The suitability of a given piece of land is its natural ability to support a specific purpose. Surface irrigation is the introduction and distribution of water in a field by the gravity flow of water over the soil surface. Irrigation water, which contain more than 3 ppm boron is harmful to the nursery plants. Surface Irrigation is an unchanged process and it is older than its recognition. Advantages of Basin irrigation, Furrow Irrigation, Well and Tube Well Irrigation and Canal Irrigation. Irrigation techniques like Surface Irrigation, Sub surgace Irrigation and Sprinkler Irrigation. Let us have a look at different types of irrigation and the methods used for irrigation. DESIGN OF SURFACE IRRIGATION, LECTURE SUPPORTING MATERIALS 3 Figure 2.1 Typical Irrigation System Components A surface irrigation event is composed of four phases as illustrated graphically in Figure 2.2. Surface irrigation methods . The main source of irrigation water in Bangladesh is groundwater, hence its quality needs to be ensured; otherwise, it can damage soil and reduce crop production. 2 The study area Wadi Baye area situated 70 Km at west of Sirte city (Northern Libya). • Method of cultivation . Main methods of irrigating crops are surface irrigation (Basin and furrow), overhead irrigation (centre pivots, conventional sprinklers), micro irrigation (drip, micro sprinklers) and sub-surface irrigation. Varied quantities of water are allowed on the fields at different … 90% of world’s total irrigated area is under this method. An important advantage of the furrow method is that only 0.2 to 0.5 as much surface area is wetted during irrigation as compared with flooding methods of irrigation, …and evaporation losses are correspondingly reduced. By using a low supply rate, deep percolation or surface runoff and erosion can be minimized. After analysing and evaluating soil properties, suitability maps were generated for both methods by means of remote sensing (RS) and a geographic information system (GIS). Read this article to learn about the important methods of irrigation, i.e., (1) Surface Irrigation (2) Overhead or Sprinkler Irrigation (3) Drip or Trickle Irrigation. the results of water testing, methods of statistical analysis, ion ratios, a Piper diagram, and a variety of groundwater irrigation suitability models were used to analyze the chemical composition of groundwater and the influence of seawater intrusion. Surface Irrigation is a kind of irrigation where gravity works its best. Still the suitability of the water for different purposes needs to be verified. The classification of water on the basis of E.C. the study area [3]. Throughout the world, this is the most commonly used type of irrigation process. The resultant map can assist decision makers in ensuring that lands are used according to their suitability. The main objective of this research was to compare the suitability of land for surface and drip irrigation methods according to a parametric evaluation system in the plains west of the city of Shush, in south-west Iran. For land suitability analysis of surface irrigation, particular attention is given to the physical properties of the soil, distance from available water sources and terrain conditions in relation to methods of irrigation considered [7]. Surface irrigation is widely utilised and therefore a well-known system, which can be operated without any high-tech applications. The soil acts as the growing medium in which water is stored and the conveyance medium over which water flows as it spreads and infiltrates.
