“…Although the recognized Kostiakov equation has provide a poor description of the infiltration characteristic and limits the accuracy of the simulations for many soils, this may be satisfactory for surface irrigation with short ponding times when the expression adequately estimates accuracy where the opportunity time does not exceed 3 to 4 hours (Walker et al, 2006). This is confirmed by the good agreement between the simulated and measured advance trajectory values for each furrow (Fig.…”

“…The water infiltration depths in the soil, which were recorded against time, were used to calculate the parameters in the infiltration equations for each on-time. The simplest and most commonly used approximation for infiltration is the Kostiakov equation which can be written in general terms for furrow irrigation as (Walker et al, 2006):…”

A b s t r a c t. Surge flow irrigation is one of the irrigation techniques for controlling furrow irrigation. The aim of this study was to investigate the effect of surge furrow irrigation on water management compared with continuous irrigation for different tillage systems. An experimental field was treated with various tillage systems (mouldboard plough, chisel plough and rotary plough) and water irrigation application methods (continuous flow, control) in which irrigation water was applied continuously, and surge flow (3-surges, 4-surges and 5-surges) in which irrigation water was applied intermittently until it reached the tail end of the furrow. The results showed that water savings obtained using the surge technique were 18.58, 11.84 and 18.93% lower water use than with continuous flow, for the mouldboard, chisel and rotary ploughs, respectively. The 3-surges treatment with the rotary plough reduced the advance time by 25.36% from that for continuous irrigation. The 4-surges treatment with the mouldboard plough had the highest water application efficiency (88.13%). The 3-surges treatment with the rotary plough had the highest distribution uniformity (85.01%). The rotary plough did not cause as much soil aeration around the root system as the other tillage systems. The field research provided information about surge flow, aimed at reducing advance times and increasing irrigation efficiency.K e y w o r d s: irrigation, ploughing system, water application efficiency, distribution uniformity, advance rate INTRODUCTION

“…Because the duration of the water application in basin irrigation is small, the intake rate derived from Equation (1) does not significantly under-estimate infiltration at the end of irrigation [50]; thus, a third parameter representing the basic infiltration rate was not considered. A large number of field measurements of irrigation events in Dengkou determined six standard infiltration curves [13].…”

“…For operational purposes, following the approach by Walker et al [50], infiltration curves were clustered into three infiltration families ( (i) High infiltration rates, when the first irrigation event is described by the observed curve SC-I, the second event to the curve SC-II, and the third and following events to the SC-III curve; (ii) Medium infiltration rates, with the first event described by the curve SC-III, the second event by the curve SC-IV, and the third and following events by the curve SC-V; and (iii) Low infiltration rates, where the first irrigation event is described by the curve SC-IV, the second event by the curve SC-V, and the third and later events by the curve SC-VI.…”

Abstract:The sustainability of the Hetao Irrigation System, located in the water scarce upper Yellow River basin, is a priority considering the need for water saving, increased water productivity, and higher farmers' incomes. The upgrading of basin irrigation, the main irrigation method, is essential and includes the adoption of precise land levelling, cut-off management, improved water distribution uniformity, and adequate irrigation scheduling. With this objective, the current study focuses on upgrading wheat basin irrigation through improved design using a decision support system (DSS) model, which considers land parcels characteristics, crop irrigation scheduling, soil infiltration, hydraulic simulation, and environmental and economic impacts. Its use includes outlining water saving scenarios and ranking alternative designs through multi-criteria analysis considering the priorities of stakeholders. The best alternatives concern flat level basins with a 100 and 200 m length and inflow rates between 2 and 4 L s −1 m −1 . The total irrigation cost of designed projects, including the cost of the autumn irrigation, varies between 2400 and 3300 Yuan ha −1 ; the major cost component is land levelling, corresponding to 33-46% of total irrigation costs. The economic land productivity is about 18,000 Yuan ha −1 . The DSS modelling defined guidelines to be applied by an extension service aimed at implementing better performing irrigation practices, and encouraged a good interaction between farmers and the Water Users Association, thus making easier the implementation of appropriate irrigation management programs.
