"Changes in weather conditions impact construction activities. The consideration of effects of changes in weather condition is important to better estimate the performance of construction resources. This paper demonstrates the integration of a weather generator to support modelling earthmoving operation using distribution simulation with high level architectural (HLA) standards. The modelled earthmoving operation is related to the oil sand mining. The weather effects on the breakdown and maintenance events of earthmoving resources (trucks and excavators) were analyzed under different weather testing scenarios and their results were reported accordingly."

Coastal Sand

The commercial mining of sand at coastal locations along California has been a continuing activity at some sites, sporadic at others and altogether discontinued at still other sites. This mining activity includes all methods of sand mining (dragline, self-propelled bottom-dump scrapers, diesel shovels, etc.) and may be classified by littoral zone location as (1) mining from a beach foreshore or backshore area wetted by the normal tidal range, (2) mining within a river mouth or other estuary upstream from the ocean but still within the tidal zone, and (3) mining from bluff or dune areas not wetted by the normal range of tides but still within the littoral system. Processing of the sand thus mined takes place when the material is transported from the mining site, usually by end dump trucks or belt conveyor to either a fixed or a portable plant. Commercial uses of the sand thus mined fall into two general categories, (1) construction and (2) special purposes. Construction usage includes aggregate for concrete, asphalt, mortar, plaster and stucco, base material in road construction, and fill and structural backfill. Specialty uses include sand blasting and filtration material, foundry and engine sands, and raw material for manufacture of glass and ceramics. Within the area studied (see Figure 1) the Monterey Bay area has the highest concentration of mining activity. To the north, the area around Fort Bragg yields significant quantities to the commercial miner. Most of the remaining coastal sand mining activity is concentrated in the San Francisco area.

Abstract. The community-managed sand mining activity in Bambang Village, Wajak District, Malang Regency caused serious environmental descruptions and many did not have official permits. The land that was once fertile turned into degraded land, the level of soil fertility, often found former sand dug pits and cliffs that have relatively steep slope. Joint land rehabilitation includes land use management, erosion and sedimentation control, and revegetation and maintenance of introduced plants. Land structuring is carried out to prepare land to become land ready for planting by adopting "BioPot" technology which is preparing planting hole on the ground consisting of a mixture of clay, manure, biofertilizers and lime. Selected plants adapt to existing conditions consisting of woody plants and fruits such as: Pule (Alstonia macrophylla), Kecrutan (Spatodea campalunata), Bungur (Langerstroemia spesiosa), Avocado (Persea americana), Pete (Parkia speciaosa), Durian (Spatodea campalunata), Pucuk merah (Syzygium myrtifolium), etc. Based on the existing land conditions, the land is arranged using a blocking system and between plants 4 m x 4 m apart. This technology can be adopted well by the community and planted plants can grow and develop properly.Keywords: Land Former Sand Mining, Revenge, Biofertilizer, Pioneer Plants Abstrak. Kegiatan penambangan pasir yang dikelola masyarakat di Desa Bambang, Kecamatan Wajak, Kabupaten Malang menyebabkan kerusakan lingkungan yang serius dan banyak yang tidak memiliki ijin resmi. Lahan yang semula subur berubah menjadi lahan terdegradasi tingkat kesuburan tanahnya, banyak dijumpai lubang bekas galian pasir serta tebing yang memiliki kemiringan lereng relatif curam. Rehabilitas lahan yang dilakukan bersama mencakup penataan lahan, pengendalian erosi dan sedimentasi, serta revegetasi dan pemeliharaan tanaman yang diintroduksikan. Penataan lahan dilakukan untuk menyiapkan lahan menjadi lahan siap tanam dengan mengadopsi teknologi “BioPot” yang merupakan lubang tanam terdiri dari campuran tanah liat, pupuk kandang, biofertiliser dan kapur. Tanaman terpilih menyesuaikan dengan kondisi yang ada yang terdiri dari tanaman kayuan dan buah-buahan seperti: Pule (Alstonia macrophylla), Kecrutan (Spatodea campalunata), Bungur (Langerstroemia spesiosa), Alpukat (Persea americana), Pete (Parkia speciaosa), Durian (Durio zibhentinus), Pucuk merah (Syzygium myrtifolium), dll. Berdasarkan kondisi lahan yang ada, lahan ditata menggunakan sistem blocking dan antar tanaman berjarak 4 m x 4 m. Teknologi ini dapat diadopsi dengan baik oleh masyarakat dan tanaman yang ditanaman dapat tumbuh dan berkembang dengan baik. Kata Kunci : Lahan Bekas Tambang Pasir, Revegetasi, Biofertilizer, Tanaman Pioneer

The Social

Debris flows triggered by Merapi eruption in 2010 have impacts on the environment and social condition along the rivers on the volcano, especially in Pabelan River. Material resulted from debris flows could change on morphology and porosity of riverbed surface material, as well as the capacity of sediment. Therefore, it is important to study the influence of Merapi eruption in 2010 on environmental and social conditions in Pabelan River. To determine the river morphology was used Ronsgen method. To calculate porosity of riverbed surface material was used the equation was proposed by Sulaiman. Einstein equation was used to calculate sediment transport. To investigate the social conditions, damage land and sand mining activity were used as parameters. The result has shown that morphology types at confluence Progo-Pabelan Rivers, Srowol Bridge, and Pabelan Bridge 1 were D5b, D5b and E5, respectively. Sedimentation has occurred in the segment between the confluence of Progo-Pabelan Rivers and Srowol Bridge. Erosion has taken place in the segment between Srowol Bridge and Pabelan Bridge 1. The riverbank collapses took place along the river and it gave a negative impact on social conditions. The sand mining activity was intensive, and the activity has a positive impact on the economical inhabitants.

Erosion And Deposition

The hydro- and morphodynamic processes within the Vietnamese Mekong Delta are heavily impacted by human activity, which in turn affects the livelihood of millions of people. The main drivers that could impact future developments within the delta are local stressors like hydropower development and sand mining, but also global challenges like climate change and relative sea level rise. Within this study, a hydro-morphodynamic model was developed, which focused on a stretch of the Tien River and was nested into a well-calibrated model of the delta’s hydrodynamics. Multiple scenarios were developed in order to assess the projected impacts of the different drivers on the river’s morphodynamics. Simulations were carried out for a baseline scenario (2000–2010) and for a set of plausible scenarios for a future period (2050–2060). The results for the baseline scenario indicate that the Tien River is already subject to substantial erosion under present-day conditions. For the future period, hydropower development has the highest impact on the local erosion and deposition budget, thus amplifying erosional processes, followed by an increase in sand mining activity and climate change-related variations in discharge. The results also indicate that relative sea level rise only has a minimal impact on the local morphodynamics of this river stretch, while erosional tendencies are slowed by a complete prohibition of sand mining activity. In the future, an unfavourable combination of drivers could increase the local imbalance between erosion and deposition by up to 89%, while the bed level could be incised by an additional 146%.
