Simulating the changes of water table depth in coastal saline land with agro-subsurface drainage system

An estimation of optimal design parameters of subsurface drainage system through monitoring of water table depths and drain discharges are expensive in terms of time and money. The simulation modeling is an effective tool for estimation of drainage design parameters at less cost and short time. In view to this, calibration of DRAINMOD model for prediction of water table depths and drain discharges were conducted by installing subsurface drainage system with 40 m drain spacing and 1.0 m drain depth at Agricultural Research Station, Kasbe Digraj, Dist. Sangli (Maharashtra) during 2012-13 to 2013-14. The field data on water table depth and drain discharge were used for calibration of DRAINMOD model. The input data files on climatic, soil, crop and drainage design system parameters were attached to DRAINMOD model and calibrated successfully. It is found that both observed and simulated water table depths and drain discharges showed a fluctuating trend and predicted both water table depths and drain discharges closely with the observed values during frequent rainy days and following the rainy days. The DRAINMOD model reliably predicted water table depths with a goodness of fit (R2 = 0.97), MAE (12.23 cm), RMSE (15.49 cm) and CRM (0.05); drain discharges with R2 of 0.93, MAE of 0.095 mm day-1, RMSE of 0.1876 mm day-1and CRM of 0.04. Thus, the calibrated DRAINMOD model can be used to simulate the water table depths and drain discharges in semi-arid climatic conditions of Maharashtra and in turn to estimate and evaluate drain spacing and depth.

Dagan?s method as well as Kirkham?s one belong to the group of methods for drain spacing determination in steady state water flow conditions. Both methods are based on the assumption that drainage spacing (L) is linear function of water table depth and drainage discharge (h/q). The only difference can be distinguished in the values of coefficients. To dry out eugley type of soil, drain spacing is better determined by Dagan?s method in all treatments, as compared with Kirkham?s one. Advantage of this method is especially marked on the drainage system with narrower drain spacing.

O presente trabalho teve como objetivo estudar o comportamento do lençol freático e o fluxo de drenos, em cinco anos extremos, que apresentam baixa, média e elevada pluviosidade anual, na cidade de Piracicaba-SP. O estudo foi realizado utilizando o software de Sistema de Drenagem - SISDRENA. Foram avaliados uma série temporal de cinco anos, com pluviosidade média anual abaixo, próxima e acima da média histórica para a cidade de Piracicaba, SP, Brasil. A partir destes anos, realizou-se a estimativa da altura do lençol freático e do fluxo de drenagem para cada um desses períodos, em cada tipo de solo estudado, com texturas Franco-argilosa, Argilosa e Franco-argilo-Siltosa. Foram realizadas simulações com diferentes espaçamentos entre drenos, variando de 10 a 100 m, a uma altura inicial de 0,55 m, para a cultura do milho (Zea mays). Em solos com menor coeficiente de drenagem, ocorre a diminuição do fluxo de drenagem a partir do espaçamento de 20 m. Em períodos chuvosos, com elevada pluviosidade anual, ocorreu uma maior altura do lençol freático para os três tipos de texturas de solos estudados. Palavras-chave: Irrigação; Sisdrena; Infiltração.

DUARTE3ESTIMATING DRAINAGE FLOW AND WATER TABLE DEPTH FOR YEARS WITH LOW MEDIUM AND HIGH RAINFALL 2 ABSTRACT Excessive water in the soil, due to seasonally or periodically high water table levels, is often the main factor limiting crop yield. Water table depth can indirectly affect plant growth and development, due to adverse moisture, aeration soil and thermal conditions in the soil profile. The aim of this study was to evaluate the water table depth and the drain flow for five year periods with low, medium and high annual rainfall. The study was conducted using the Drainage System software - SISDRENA. Water table depth and drainage flow were simulated in three soils (Franco-clay, clay and Franco-silty-clay) for each one of these periods. Simulations were performed for maize (Zea mays), with drain spacing ranging from 10 to 100 m and an initial water table height of 0.55 m. In soils with lower drainage coefficient, there was decreased drain flow when the drain spacing exceeded 20m. During rainy periods, with a high annual rainfall rate, the water table was elevated in all three soil types. Keywords: Irrigation; Sisdrena; Infiltration.

ABSTRACT This paper presents the results of the evaluation of contamination in the Saldanha Creek basin, caused by an oil spill at Refinaria Presidente Getúlio Vargas belonging to PETROBRAS, in Araucária – state of Paraná, which occurred on July 16, 2000. The oil reached Saldanha stream following 4 distinct paths and, over its course, overflowed the canal banks contaminating a total of 17.70 hectares of existing wetlands. The oil infiltration into the subsoil occurred in two main areas: (1) around the scraper, which is where most of the oil was infiltrated (approximately 43,000 liters of oil in free phase); (2) in Wetland 4, where the contaminant is mainly adsorbed to the soil particles. The characteristics of the former favor the implementation of a subsurface drainage system, with an oil separator. In the second, flooding the area would allow the removal of part of the contaminant by a difference of density, and part with a reactive barrier to which the groundwater flow would be induced.

Drain Spacing

The field experiment was conducted at Agricultural Research Station, Kasbe Digraj, Dist. Sangli during Adsali sugarcane season of 2012-13 to 2013-14. The experiment was conducted by installing subsurface drainage system with 10, 20, 30 and 40 m drain spacing and 1 m drain depth. In view of different costs and effectiveness of subsurface drainage associated with the varying depths and spacings, field evaluation of unsteady drain spacing equations was important for finding out the optimal drain spacing equation among various equations. The field evaluation of unsteady drain spacing equations revealed that the van Schilfgaarde, Hammad, Modified Glover, Guyon and Integrated Hooghoudt’s equation performed satisfactory for estimation of water table depths among seven unsteady drain spacing equations. The Glover-Dumm and Modified Glover-Dumm’s equations were not performed satisfactory for estimation of water table depths. Among unsteady drain spacing equations, van Schilfgaarde’s equation performed better and hence recommended for water table depth estimation and in turn for optimal design of subsurface drainage system under waterlogged Vertisols of Maharashtra.

Good Drainage

Integrated water management has become a priority for cropping systems where subirrigation is possible. Compared to conventional sprinkler irrigation, the controlling water table can lead to a substantial increase in yield and water use efficiency with less pumping energy requirements. Knowing the spatiotemporal distribution of water table depth (WTD) and soil properties should help perform intelligent, integrated water management. Observation wells were installed in cranberry fields with different water management systems: Bottom, with good drainage and controlled WTD management; Surface, with good drainage and sprinkler irrigation management; Natural, without drainage, or with imperfectly drained and conventional sprinkler irrigation. During the 2017–2020 growing seasons, WTD was monitored on an hourly basis, while precipitation was measured at each site. Multi-frequential periodogram analysis revealed a dominant periodic component of 40 days each year in WTD fluctuations for the Bottom and Surface systems; for the Natural system, periodicity was heterogeneous and ranged from 2 to 6 weeks. Temporal cross correlations with precipitation show that for almost all the sites, there is a 3 to 9 h lag before WTD rises; one exception is a subirrigation site. These results indicate that automatic water table management based on continuously updated knowledge could contribute to integrated water management systems, by using precipitation-based models to predict WTD.
