Soil Water Engineering Field and Laboratory Manual

Contents: Foreword. Preface. 1. Soil Bulk Density. 2. Soil Particle Density And Prosity. 3. Particle-Size Analysis. 4. Soil Water Holding Capacity. 5. Soil-Water Content. 6. Soil-Water Capillary Pressure. 7. Hydraulic Conductivity. 8. Field measurement of hydraulic Conductivity By The Auger-Hole Method. 9. Infiltration. 10. Soil Salinity. 11. Water Measurement. 12. Measuring Weather Parameters. Appendices: 1. Repeatedly Used Laboratory Equipment. 2. Statistical Analysis Of Measurements. 3. Laboratory Report Guidelines. 4. Unit Conversions. This manual is designed to teach basic methods for measuring the soil-water properties most important to irrigation and drainage engineers. The first three exercises describe methods to measure soil properties which affect the soil water. The following three exercises describe methods to measure soil water. Exercises 7, 8 and 9 describe methods to measure parameters which affect soil-water movement. The final three exercises describe measurements which help to determine the quality of soil water for plant use, and the inflows to and outflows from the soil-water reservoir.…
